Pros:

Good model, texture.
Level of shiny, reflection proper. (latter is rare)
Proper world placement.
Decently animated.

Cons:

Poor sound quality. Fire cuts off, audible pops at beginning of mag insert, lever pull.
Hud Icon broken. (script width 64, should be 192)
No flashlight, laser attachments. Gas barrel tip is an acceptable substitute.

Conclusion:

A wellfitting replacement for the much too barren stock weapon.
The few bugs aside, a welcome addition to my model selection.
